The products were achieved in moderate to excellent yields at room temperature under air. Notably, this reaction is compatible with various biomols. including amino acids, oligosaccharides, nucleosides, proteins, and cell lysates.

And the article contained the following:

A new route to benzyl thioether derivatives has been developed via the N-heterocyclic carbene palladium(II)-catalyzed cross coupling of benzylammonium salts with thiophenols. Under the optimal conditions, different benzylammonium salts could be well tolerated. Meanwhile, various kinds of aryl thiophenols and heteroaryl thiophenols could be used as efficient substrates, generating broad array of benzyl thioethers in good to high yields within hours.

On January 11, 2018, Su, Ji; Chen, Qian; Lu, Le; Ma, Yuan; Auyoung, George Hong Lok; Hua, Ruimao published an article.SDS of cas: 321-28-8 The title of the article was Base-promoted nucleophilic fluoroarenes substitution of C-F bonds. And the article contained the following:

With the use of KOH/DMSO as the superbase medium, the nucleophilic fluoroarene substitution for C-F bonds was presented. The transformation proceeds smoothly with the use of fluoroarenes such as 2-fluoro-benzamide, 3-fluorobenzaldehyde, 3,4-difluoronitrobenzene, etc. bearing not only electron-withdrawing group, but also electron-donating group and a variety of nucleophiles such as methanol, phenol, dimethylamine, 1H-pyrrole, benzamide, etc.. The double nucleophilic substitution using 3,4-difluoronitrobenzene and nucleophiles bearing ortho-dinucleophilic groups such as 1,2-ethanediol, 1,2-benzenediol, 2-amino-phenol results in the formation of 6-Nitro-2,3-dihydrobenzo[b][1,4]dioxine, 2-Nitrodibenzo[b,e][1,4]dioxine and 2-Nitro-10H-phenoxazine in moderate to good yields. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).SDS of cas: 321-28-8

On April 30, 2020, Du, Tianshu; Quina, Frank H.; Tunega, Daniel; Zhang, Jianyu; Aquino, Adelia J. A. published an article.Application In Synthesis of 1,2-Dimethoxybenzene The title of the article was Theoretical O-CH3 bond dissociation enthalpies of selected aromatic and non-aromatic molecules. And the article contained the following:

Although Me transfer reactions are important in both chem. and biol. systems, there is a need for thermodn. parameters related to Me affinity and O-CH3 bond dissociation enthalpies (BDEs) relevant to a full understanding of the mechanisms of Me transfer reactions. As a prelude to the construction of a database of O-CH3 BDEs, the present work examines the reliability of a series of theor. methods for the prediction of O-CH3 BDEs using a set of 25 compounds that included both aromatic and non-aromatic mols. The BDEs calculated by d. functional theory (DFT) with traditional exchange-correlation functions exhibited much larger errors than those obtained by either the M06-2X or G4 methods. For the non-aromatic compounds, M06-2X/def2-TZVP performed slightly better than G4, but G4 was more accurate for the aromatic mols. As a result, we recommend G4 as the preferred method for the theor. estimation of O-CH3 bond dissociation enthalpies, although M06-2X may be a good alternative for large complex mols. when the use of G4 is impractical. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Application In Synthesis of 1,2-Dimethoxybenzene
